Mallet.



CARL KNOPF, OF NEW YORK, N. Y.

MALLET.

Specification of Letters Patent.

Patented Aug. '13, 1907/ Application filed May 2, 1907. Serial No.371,427.

To all whom it may concern:

Be it known that I, CARL KNOPF, a citizen of the United States, and aresident of the city of New York, (borough of Brooklyn,) in the countyof Kings and State of New York, have invented a new and Improved Mallet,of which the following is a full, clear, and exact description.

This invention relates to certain improvements in mallets especiallyadapted for use of workers in soft metal, as, for instance, tinsmiths,coppersmiths, and the like.

The object of the invention is to provide a double faced mallet havingthe head formed of two separate pieces of non-metallic material, as, forinstance, wood, so constructed that they are rigidly held in place bythe insertion of the handle, and so formed that the metallic inclosingsheath or casing cannot come in contact with the article being poundedinto shape by the mallet.

The invention consists in certain features of construction andcombination of parts, all of which will be fully set forth hereinafterand particularly pointed out in the Claims.

Reference is to be had to the accompanying drawing forming a part ofthisspecification, in which the figure illustrated is a centrallongitudinal section through a device embodying my invention.

In my improved mallet, I provide a hollow openended casing having thetwo oppositely disposed members going to make up the head, rigidlysecured therein by means of the handle. The sheath 0r casing 10 ispreferably formed of metal and may be cylindrical in form, or providedwith slightly divergent ends and contracted intermediate portion, asillustrated in the drawings. This casing serves to support the twoopposite members 11 and 12 which make up the head proper, each of thesemembers being provided with cylindrical or somewhat tapered shankportions 13 extending into the opposite ends of the casing. Each ofthese shank portions terminates in a beveled or inclined face 14, andeach shank extends a considerable distance beyond the center portion ofthe casing, the beveled or inclined face of one head member engagingwith the corresponding face of the opposite head member. Theintermediate portion of the casing is provided upon opposite sidesthereof with openings, and the overlapping end portions of the headmembers are provided with corresponding openings adapted to be broughtinto alinement with the openings in the casing. With the two headmembers forced inward into the casing to the limiting position andproperly disposed in relation to the casing, the openings are allbrought into alinement to permit of the insertion of the end of thehandle 15.

The inserted end is preferably slightly tapered, and the openings in thehead members may, if desired, be slightly elongated to facilitate thewedging action and draw the head members into firmer engagement witheach other and the surrounding casing. Each head member is provided witha curved face merging into a curved circumferential flange 16 ofmaterially larger diameter than the casing 10. The surface of the flangemerges into the surface of the shank portion, and due to the expandednature of the ends of the casing and the wedging action due to theinsertion of the handle, the head members may be drawn very firmly intoengagement with the casing. By making the flanges 14 of larger diameterthan the casing, it is practically impossible to bring any portion ofthe metal casing 10 into engagement with the material operated upon.

The mallet above described is particularly adapted for the use oftinsmiths, coppersmiths, and other workers upon metals malleable atordinary temperature. In working upon these metals even a slight blowfrom an iron tool leaves a mark or blemish which is very difficult toremove. The flanges 16 of my improved mallet thoroughly protect themetal from the edges of the casing, as will be readily understood. Assoon as the surface of either of the head members wears away to such anextent as to affect the efliciency of the tool the head member may bereadily removed and replaced by a new one by simply removing the handle15.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A mallet, comprising a hollow cylindrical casing having open ends,oppositely disposed head members having shank portions extending intothe ends of said casing. and a handle in engagement with the shankportion of each of said heads for holding the same within said casing.

2. A mallet, comprising an open ended casing, oppositelydisposed headmembers having shank portions extending into the ends of said casings,said shank portions being provided with transverse openings, and ahandle extending through said openings and serving to hold said headmembers within said casing.

3. A mallet, comprising an openended casing, oppositelydisposed headmembers having overlapping inner ends, and a handle extending; throughthe overlapping ends to hold the head members.

4. A mallet, comprising an open-ended casing, oppositely disposed headmembers having overlapping inclined inner ends, said ends and easinghaving an opening there through and a handle extending through saidopening and serving to hold said members and easing rigid in respect toeach other.

5. A mallet, comprising an open-ended metallic casing having oppositelydisposed head members, each havinga shank portion extending into saidcasing with a transverse opening through said shank and having anoutwardly-extending flange adjacent the corresponding end of the casing,and a handle extending through the openings in said shank portions andthrough an opening in said casing for holding the head members andeasing rigid in respect to each other.

G. A mallet, comprising an open-ended casing, head members having shankportions extending into said casing and having outwardly extendingflanges adjacent the ends of the casing, the inner ends of said shankportions terminating in inclined surfaces overlapping each other andhaving an opening, and a locking member extending through said openingsfor locking the head members in 10 position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
